My wife is the cat person and she told me and it just so happens that our retired Vet, I lease hay ground from him and I asked him about it and he said it was true, that most all cats are lactose intolerant. Not all, but most. Hay is the farthest thing from my mind presently. Staying warm and keeping the bird feeders full is an almost full time job presently. It's super cold here which is actually good because it kills of the over wintering pests I have to spray for in the spring so it saves me the cost of chemicals.
We don't have a lot of snow either but you do Lou, you are on the other side of the Great Lakes snow machine.
We might have 4" on the ground, nit enough to even be concerned about. What is concerning is the ice that formed prior to the snow that is coating the roadways and it's so cold here that conventional treatments don't work. Lots of people going in the ditches, including my wife, she slid off the edge of the drive with her Suburban and got stuck and I had to call the local recovery company to winch it out. Was gonna use the tractor but where she slid off, there was no way I could get near enough to her vehicle to use a snatch strap on it so I digressed and paid the local tow company a hundred bucks (from her checking account) to pull it out. Under the snow covering it was all mud.
